-NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 656,068, dated August 14, 1900. Application filedJ'anuary 10,1900. Serial No. 915. (No modeh) T0 at whom it may concern: 7

Be it known that I, ASA W. WEBB, of South Union, in the county of Loganand State of Kentucky, have invented a new and useful Improvement in Nut-Locks, of which thefol lowing is a specification;

My invention 1s an improvement in looks, and has for its object a device for preventing the unscrewing of nuts which does not need a nutof special construction, but can be used with any of the ordinary forms of bolts and nuts.

The invention consists in certain details of construction, which I shall hereinafter specificall y describe and claim.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which like characters of reference indicate corresponding parts in all theviews.

Figure 1 is a perspective view of a portion of a railroad-tie with' 'ni y improved nut-lock in place. Fig. 2 is a side elevation thereof,

illustrating the lock-bar in place and the nuts lock is adapted to be placed, as shown in Fig. 1, and it consists of a lock-bar 10, having a flat face 11, adapted to lie against the fishplato, and angular notches 12 at each end, the rear wall of each notch being beveled, as

at 13, and parallel with the opposite corre-.

sponding wall of the other notch.- The opposite side faces of the lock-bar 10 are also bev eled at the ends, as shown at14. To look the nut-' j nuts after they are screwed up tightly, the

bar 10 is placed diagonally on the fish-plate A, with its ends lying underneath adjacent nutsand the bevels 14 abutting against the washers, as shown in Fig. 2. .One nut is then turned back slightly, so as to" bring its side face tightly against the beveled rear walls of the notches, as shown in Fig. 3, when the nuts will be locked and prevented from turning farther backward so long as the lock-bar 10 is in place.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A nut-lock for twonuts, comprising a lock-bar having notched ends adapted to engage the inner and side faces of the nuts, the rear walls of the notches being inclined in parallel planes oblique to the length of the bar,whereby a backward turn of the nuts will bind their side faces against such rear walls, as set forth. V

2; A nut-lock for two nuts,comprising a lock-bar adapted to lie against the fish-plate or the like and having notched ends arranged to fit against the inner and side faces of the nuts, the rear walls of the notches being inclined or beveled in parallel planes oblique to the length of the bar and the side faces of the bar being also beveled. whereby to lie snugly against the washers of the nuts, as set forth.

In testimony whereof; I have signed my name to this specification in the presence of two subscribing witnesses.
